Electroaerodynamics new plane flies using this technique

The blue glowing jets of science fiction spacecraft came a step closer to reality on Wednesday as US physicists unveiled the world's first solid-state aeroplane powered in flight by supercharged air molecules.

More than a century on from the Wright brothers' first artificial flight, scientists hailed the "historic" test of the new technology, which could eventually slash greenhouse-gas emissions from aviation....

Problem with current technology, is that superconductors cannot operate at room temperature and battery technology cannot store enough energy. I believe the boat was powered by a generator and it would have greater performance if the generator had been used to turn a propeller rather than generate electricity.

May be in the future when we have room temperature superconductors and batteries with greater storage capacity, this sort of technology will take off.
